The 2014 F1 season may be away by a couple of months and the cars are still in innovation mode but the driver's have all made their choice of numbers for next season.

According to one of the new rules of the sport, drivers get to choose their numbers and the allotment system will be stopped from this year.

No1 will be reserved for the F1 World Champion of the previous season who has a choice about whether he wants to use it or not but no one else can take the number.

Current F1 champion Sebastian Vettel will use No1 on his car this season but if he is unable to defend his title and has to let go of the number he has opted for No5.

The drivers have to use the numbers they have chosen for the rest of their careers. The new rule has been agreed upon to help the sport commercialise the drivers. All drivers were asked to submit three numbers in order of preference and any clashes were decided by last year's drivers' championship standings.

Max Chilton who was just confirmed by his team yesterday, has not yet chosen his number and the Caterham team have yet to announce their driver line up.

As F1 fans wait for the five red lights of the 2014 F1 season to illuminate, the testing will start soon showing off the new cars and drivers in action as they tweak the new challengers for race and championship wins.
